STAY-ROLLER FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 267,832, dated November 21, 1882.

' Application filedOetober- 'i, 1882. (Merlot) Be it known that I, WARREN M. BRINKER- HOFF, a citizen of the .United States, residing at Auburn, in the county of Uayuga and State' ofNew York, have invented new and useful Improvementsin Stay-Roller Supports forSliding Doors, of which the following is a specification. t

This invention relates to improvements in stay-rollers for sliding doors of that character wherein a shank adapted to besecured to the timber of the building at the lower end of the doorisprovrded at its outer-end with ajournalarm on which aroller or wheelis arranged to rotate in a horizontal plane, such roller or wheel resting in front of the lower edge of the sliding door for retaining it in proper relative position to the building.

Stay-rollers as heretofore constructed have been composed of ashank with no provision to prevent its rotation and consequentdisplacement of the stay-roller from its proper working position against the lower front edge of the sliding door.

The object of my inventionis to avoid this objection and provide simple and efficient means for preventing the shank from turning after being secured in position, and thereby retain the roller or wheel in its proper place, and prevent its accidental displacement after being once adjusted into the position it is to occupy.

To this end my invention consists in constructing the shank of angular shape in crosssection between thejournal-arm ot' the roller or wheel and theinner termination ofthe screwthread or pointed end, on which is arranged a locking-washer or plate having a perforation corresponding to the angular cross-sectional form of the shank, such washer or plate, after the shank and roller are in position, being suitably secured in a fixed position to the timber into which theshank is secured. Hence theshank cannot turn or rotate, owing to the stop afl'orded by the edges of the angular perforation in the washer or plate, which act against the angles formed by the cross-sectional form of the shank.

The invention is illustrated in the accompanying drawings, in which Figure 1 is aperspective view, illustrating my invention Fig. 2, a side elevation of the parts in position for use, the timber ofthe building and sliding door beingin section Fig. 3, a cross-section through the angular part of the shank or support; Fig. 4, a plan view of the locking washer-or plate; Fig. 5, a perspective view, showing a modification of the invention; Fig. 6, an enlarged cross-section through the angular part of the shank shown in Fig. 5, and Fig. 7 an enlarged plan view of the washer shown in Fig. 5.

Referring to the drawings, the number I indicates the shank or support for the stay-roller, said shank or support having at one end a screw-thread, 2, which extends about one-third the length thereof, and is provided with a gimlet or other suitable point, 3. The other end of the shank or support is bent or otherwise constructed to provide a journal-arm, 4, arranged at right angles, or substantially so, to the body of the shank or support, which journal carries a roller or wheel, 5, capable of freely revolving, and confined in place by a head, 6, or other means at the end of the journal-arm, which projects through the bore of the wheel. As shown in Figs. 1 and 2, the shank between the inner termination of the screw-thread or pointed end and the journal-arm is of angular form in cross-section, in the present instance having four sides, 7, 8, 9, and 10, and rounded corners. The washer or plate 11 is provided with a perforation corresponding in form, or approximately so, to the angular form of the that a portion of the angular shank has entered the timber, after which the washer or plate is pushed against the surface of the timber, and there secured by screws or other suitable devices, which firmly hold it in a stationary position. The stay-roller or wheel 5, as before stated, is arranged to bear against the front lower edge of the sliding door, (see sectional view, Fig. 2) in such manner as to guide, hold, and permanently retain the slidi n g door against the wall of the building, or in any proper relative position thereto. It will be obvious from the foregoing that the edges of the angular perforation in the washer or plate act as stops against the angles formed by the cross-section- 2 aeasaa al form of the shank or support, hence as long as'the washer or plate remains in a stationary position it will be impossible for the shank or support to turn or rotate in theleast. By this means I provide a simple construction for re taining the stay roller or wheel in its proper relative position, and prevent it from swerving out of its true path or turning upside down, and thereby the roller is always held in a horizontal positiomand squarely and evenly against the door.

In Figs. 5, 6,and7 I have illustrated a modified means of preventing the shank or support from turning in its socket after being secured therein. This modification consistsin providing theshank orsupport with longitudinal grooves 12, which in this form of, the invention constitute the angular cross-sectional shape of the shank or support. The washer or plate adapted to this construction is provided with a perforation the edges of which have inwardly-projecting lugs 13,which constitute in thisinstance the angular perforation in the washer or plate. When these parts are placed in position and the washer or plate secured in its fixed position, the lugs rest within the grooves and act as stops to prevent the shank or support from turning in its socket.

It will be obvious that many modifications will suggest themselves for attaining the desired objectsuch, for example, as making the shank oval,triangular, ribbed or fluted, or otherwise angular in cross-sectionthe perforation in the washer or platenecessarily being of an angular form to adapt itself to the crossseetlonal angulart'orm of the shank or support. I do not therefore wish to be understood as confining myself to the particular shapes or constructions illustrated in the accompanying drawings, it only being essential in carrying out my invention to provide the shank, with angles adapted to abut stops provided at or by the edges of the perforations in the washer or )late.

1 It will be obvious that the shank can be driven or otherwise secured in the timber, instead of providing it a with a screw-thread to screw it in place.

Having thus described my invention, what I claim is 1. Ashankorsupportforslidingdoors,having at one end a guide or stay wheel or its equivalent to rest against a sliding door, and provided with an angular body for receiving a looking washer or plate having a perforation constructed to act as a stop and prevent the shank or support from turning in its socket when placed in proper position, substantially as described.

2. The combination ot'a screw-threaded shank or support having at one end a loosely-journaled guide or stay roller or wheel, and constructed angular in cross-section between the screw-thread and the roller, with a washer or plate having an angular perforation and adapted to be secured in a fixed position to prevent the shank or support from turning in its socket, substantially as described.

3. The combination of a shank havingat its end an arm on which is journaled a stay roller or wheel, and having its body portion angular in cross-section, with a locking washer or plate having an angular perforation adapted to be securedin a fixed position, and thereby prevent the shank or support from turning in the socket, substantially as shown and described.

In testimony whereof I have hereunto set my hand In the presence oftwo subscribing witnesses.
